In cryptography, the tabula recta (from Latintabularēcta) is a square table of alphabets, each row of which is made by shifting the previous one to the left. The term was invented by the German author and monk Johannes Trithemius in 1508, and used in his Trithemius cipher.
Trithemius cipher
The Trithemius was published by Johannes Trithemius in his book Polygraphia, which is credited with being the first published work on cryptology.
It uses a letter square with the 26 letters of the alphabet following 26 rows of additional letters, each shifted once to the left. This creates 26 different Caesar ciphers.
The Trithemius Cipher and the Tabula Recta – Let's Create and Break Them
#cryptology, #cryptography, #cryptanalysis
In this video, I introduce the "tabula recta" and the "Trithemius cipher". Both are shown and used in Johannes Trithemius famous book "Polygraphiae". The Trithemius cipher is one of the first polyalphabetic substitution ciphers, which is created using 24 shifted alphabets. It is much more secure than using a simple Caesar cipher, but it lacks of a key. If it is known, that the Trithemius cipher was used for encryption, the decryption is easily possible.
First, I give a short overview of Johannes Trithemius life. Trithemius was a famous Benedictine abbot, a polymath and cryptologist. After that, I introduce the tabula recta and the Trithemius cipher. Then, we create a tabula recta in CrypTool 2 as well as encrypt and decrypt using the Trithemius...

Programming the Tabula Recta
published: 05 Apr 2020
Encrypting a secret text with the Vigenère cipher and the Tabula recta
The Vigenère cipher is a method of encrypting alphabetic text using different cipher alphabets for each letter, determined by a key phrase. It is therefore a special case of a polyalphabetic substitution. This encryption method was first described by Giovan Battista Bellaso in 1553. In the 19th century, the scheme was misattributed to Blaise de Vigenère (1523–1596) and so acquired its present name.
The cipher is easy to understand and implement, and it resisted all attempts to break it until 1863, three centuries later. This earned it the description le chiffrage indéchiffrable (French for 'the indecipherable cipher').
